Popis: As the population worldwide ages, the epidemic of kidney disease will also increase. Anti-neutrophil cytoplasmic antibodies (ANCA) positive rapidly progressive positive glomerulonephritis (RPGN) is the most common etiology for biopsied patients among the very elderly. Its pathological features and clinical course are well described, though there is still debate about the mechanism of injury involved in individual patients. From very ancient times, the cornerstone of treatment historically has been high-dose cyclophosphamide and a lengthy course of high-dose corticosteroids. Although this regimen has diminished the immediate mortality rate of RPGN, its intermediate and long-term adverse effects are not insignificant. Attempts to minimize toxicity and improve efficacy have been made through the years to allow physicians some options for therapy. Lower cumulative cyclophosphamide regimens, shorter corticosteroid courses, and the introduction of rituximab have modified the armamentarium for treatment of ANCA positive RPGN. As progress is made in understanding the molecular pathogenesis of this disease, new targets will be found for potential therapeutic attack. The complement system is an area of active interest for all glomerular diseases at this time. Indeed, animal studies and preliminary human studies suggest that targeting the complement system can ameliorate the course of ANCA-positive RPGN. Hopefully, as the population ages, we will see more and safer therapeutic options to treat this once rapidly fatal disease.
